I use react-native-bluetooth-escpos-printer package in my react native app. It's working fine with up to Android 11 version and Bluetooth 5.0 version, But the latest version of Android 12 & Bluetooth version 5.2 suddenly app closes. I think it's not supported by Android 12& Blutooth 5.2. If you find any solutions kindly let me know
I tried to print bill with use of react-native-bluetooth-escpos-printer but not working in blutooth 5.2

The idea of using Delphi to develop a mobile app is appealing to us because we can do Android, iOS and Windows without duplicating work. Delphi is also a language that we are familiar with. However after trying to get a simple test app running on an iPad, I do not think it is actually realistic. Here are my observations:
The iPad is running iOS 12.0.1 (and iOS 12.1 is already downloaded and ready to install).
Xcode, which runs on the mac, is used by Delphi for building apps and deploying them to the test target. Each Xcode version supports exactly one iOS SDK version and is the Xcode version plus 2. My old Mac is currently running xcode 8.2.1 so that corresponds to iOS SDK 10.2, which should run on iOS 10.2 and higher.
Delphi Tokyo supports iOS SDK versions from 8.0 up to 11.3 (so Xcode 6 to 9). It will not compile apps using SDK 12. The Xcode version running on the mac fits squarely within this range of versions.
It appears that Xcode is not able to properly support iOS versions that are newer than itself. When trying to run the application it errors out with "unable to location DeviceSupport directory for the connected device. Please check Xcode installation path and run Xcode devices". Under "Devices" the following is displayed for the iPad: "This iPad mini2 is running iOS 12.0.1, which may not be supported by this version of Xcode".
So, it would appear that the latest Xcode version is required to support the iPad running iOS 12.x but that means that Delphi cannot compile for it because it only goes up to SDK 11.3 and not 12. I do not think it is possible or sensible to downgrade the iPad iOS. Also even if we get a Delphi version that works, the next iOS update will require a new Xcode and therefore a new Delphi version that isn't even available. When the new Delphi version is finally available it will already be obsolete since iOS will have already moved on.
Please correct me where I am wrong. Because this cannot surely be the state of things.
I created app using Lua language using Corona SDK and when I try to
create a build or Send it to App Store, it displays these errors below
UNSUPPORTED IOS SDK Mismatch
The version of iOS SDK (10.2) that's installed on this computer does
not match the target iOS version (10.1). You may encounter issues
building or incompatibilities at runtime.
Anyone can help me with this issue? Any help will be appreciated.
Thank you!
I had the same problem. You need to download the latest daily build from Corona Labs and then build using that version. Daily builds are found here:

From Corona blog
Changes to Xcode Requirements
Starting with 2015.2616, Corona
Simulator will be more stringent about the version of Xcode you have
installed (older versions work like before, in a less stringent
manner). In particular, when you select a particular target iOS
version, you must have the corresponding version of Xcode installed.
For example, if you want to target iOS 8.3, you must install Xcode 6.3
which includes iOS 8.3 SDK.
Also, from this post you can read that for iOS 10 SDK you need install Xcode 8. So I guess for iOS 10.2 SDK you need Xcode 8.2 (I'm not sure which one exactly will fit). What is more you need most recent version of Corona:
stable build (requires Xcode 8.1 or later, the macOS Simulator requires macOS 10.10 or later, more information) or
daily builds.
Note: I'm using only Win7 for Corona SDK.
Hello everyone I have a legacy xamarin.iOS project (built with 5.0 SDK) now i need to update some things without changing the look of the app.
After some research how to get the older SDKs to show up in the SDK Version dropdown in Visual Studio 2013 I finally got to select the 5.0 SDK (I also changed the Deployment Target to 5.0)
But when I deploy the app to my iPhone 5S running iOS 7.1.1. i get the iOS 7 Theme
Is there any way to get the app to use the old theme? (If I download the app from the store it works with the old theme, so there should be some way)
By the way on my research I read this article Using iOS 6 theme for iOS 7 app
Is it true that I cant upload apps using an older SDK? Even for app updates?
Thanks in advance for any help.
Submission to the Apple store requires that the product be compiled with the most recent released Tools (Xcode 5.1.1 at this point) and compiled with the most recent SDK (Currently 7.1)
I am using titanium studio or sdk 3.2.0, my app is running on ios 6 and also 7 devices, but not running on ios 5 device. How can i fix it? And also i want to know how to set deployment target and mini sdk version in my project?
Note that support for iOS 5.x and earlier was removed in Release
3.2.0.
You can find this document and other useful information in the appcelerator migration guide.
In order to support iOS5, you would have to compile with an older Version of the SDK, you can find a version history and the iOS versions supported here.
We developed an iPhone app using Flex SDK 4.6 some months before and it worked fine (although it is slow).
However, today the app cannot be installed after users upgrade to iOS 5.1.
Does the latest/most current Flex SDK support iOS 5.1?
Is there any project has the similar problem?
Is there anyway to handle it?
